Although many birds
may have a life that is relatively uncomplicated by disease and illness, there
are some who will not be as fortunate. Following is a listing of some common
avian conditions and diseases with brief descriptions that will help you
identify a possible problem.
Aspergillosis: A
fungal infection affecting the respiratory and digestive systems, gasping,
wheezing or vocalizations are symptoms of this infection.
Aspergillosis is caused by inhaling
mold spores found in the bird’s environment.
Pacheco’s Disease: A contagious, viral hepatitis that affects the
liver, this disease is often fatal. Pacheco’s Disease is shed in oral secretions
and feces, and birds without symptoms can pass
this virus to other birds. Signs include
anorexia, diarrhea, increased thirst and
urination, depression, lime green urates, convulsions and sudden death. A screening test is available.
Polyomavirus: A
highly contagious virus that affects the majority of the world’s parrots. Spread
via feather dust, feces, aerosols and direct contact. Symptoms include swollen abdomen, depression, loss
of appetite, anorexia, weight loss, delayed crop emptying, regurgitation,
diarrhea, dehydration, feather abnormalities hemorrhages under the skin,
dyspnea, polyuria, ataxia, tremors, paralysis, or acute death.
A vaccine is available.
Psittacine Beak and
Feather Disease (PBFD): A fatal disease that is communicable to other birds. Feather loss, abnormal
feather growth, lesions on the beak and a general look of ill health are common
symptoms. A screening test is available.
Proventricular
Dilation Disease (PDD): A contagious viral
disease whose symptoms include weight loss, constant or intermittent
regurgitation, depression, passing undigested seed in droppings along with a
foul smell. Neurological symptoms can include seizures and weakness in the legs.
Psittacosis: A bacterial illness caused by the bacterium
Chlamydophilia, it is also potentially contagious to humans. It causes
respiratory distress and is passed through contact with an infected bird's
droppings and secretions. Treatable if caught
early. Symptoms include diarrhea, decreased appetite, sneezing, green urine,
labored breathing, sinusitis and nasal
discharge.
By becoming
familiar with this short list of common illnesses, you may be able to recognize
the early signs of a devastating disease and improve your bird’s chances of
recovery.
